Cokin Z PRO 100mm Filter Holder

Took this on a trip with my medium format kit and the wide-angle clearance below 20mm saved me from any vignetting, which was my biggest worry. The slots hold the filters securely without any annoying play.

The 100x150mm slot is perfect for my wide glass filters, and the tension lock actually holds them snug without any accidental slips. I tested it on a 17mm lens and the edges stay clean, no dark corners creeping in. Solid build that just works.

Finally, a holder that doesn't vignette on my ultra-wide lens. The slot is perfectly snug for my 100x150mm filters, and swapping them in the field is quick. Exactly what I needed for my medium format setup.
